GitLab, January 31

GitLab's popular online code repository, GibLab.com, suffered an 18-hour service outage that ultimately couldn't be fully remediated. The problem resulted when an employee removed a database directory from the wrong database server during maintenance procedures.

Some customer production data was ultimately lost, including modifications to projects, comments, and accounts.

"Our best estimate is that it affected roughly 5,000 projects, 5,000 comments and 700 new user accounts," the company said in a post-mortem.

In an apology to users, GitLab's CEO said "losing production data is unacceptable."
